HOMEWORK 2 Computational thinking

Q1. Which of the following is not done by abstraction?

• Identifies essential details
• Disregards non-essential information
• Breaks the problem down into smaller tasks

Q2. Which of the following is not done by decomposition?

• Allows multiple people to work on the problem together
• Disregards non-essential information
• Breaks the problem down into smaller tasks

Q3. Decomposition allows the entire task to be completed as _____

• A Team
• A Whole
• Quickly as possible

Q4. Identifying the steps involved in solving a problem

• Abstraction
• Decomposition
• Pattern Recognition
• Algorithmic Thinking

Q5. Why do we need to think computationally? (multiple answers)

• To help us think like a computer
• To help us solve problems efficiently
• To help us solve problems slowly

Q6. Which of these is an example of decomposition?

• Breaking the problem of organising a cake sale into smaller parts, such as who will bake the cakes and when to hold the cake sale
• Taking the problem of baking a cake and thinking about how we can make it the best cake possible
• Looking at what different kinds of cake can be made

Q7. Which of the following contains a pattern?

• All cars have wheels
• My car is blue
• My friend's car has an MP3 player

Q8. Which of these would not be involved in decomposing a problem?

• Thinking about how the problem could be divided into smaller parts
• Working out who could help you solve a part of the problem
• Adding more parts to the problem so it becomes more complaex
